In the drawings, A represents the cable, which may be constructed of anysuitable ma terial and in any preferred way, and can be mounted onproper supports between the terminalsas, for instance, in the mannershown in my previous patent, No. 269,525, September 26, 1882. I

The terminal wheel is represented, generally, by the letter B, itbeingsecured to a shaft, D, mounted in a suitable framing.

, The wheel B may be provided with any preferred means for gripping thecable; or, so far as the other features of this case are concerned, thiswheel may be a plain one-that is, may be used without supplementalgripping devices.

I have shown devices which are adapted to grip the plain portions of thecable, and also adapted to yield when the clips which carry the bucketscome in contact with them,whereby I insure that said clips and the cableshall not be thrown out of proper place.

' The gripping devices shown consist of a series of levers andleversupport of the character of that shown detached in Fig. 5. In saidfigure, B represents the shank of a lever, and b the toe orupwardly-projecting part. The lever is supported in a frame, 13 b bymeans of a pivot or cushion, as at b". To permit the adjustment of thetoe of the lever, I combine with it a set-screw, V, which passesthrough. a threaded sleeve, b, and bears against the stationary part bit being locked in place by a nut, 12*. Preferably each of these leversprojects through an aperture in the up wardly-rising flange A on theterminal wheel, as will be seen by examining Figs. 1 and 2. The toesproject outwardly just above theline of the cable, and there is atapering space be low the outer end of each into which the cable crowds,and therefore the friction upon the cable is increased.

In Figs. 1 and 2 all of the details of these Fig. 19 is a sectiongripping devices are not shown, there being merely sufficient in saidfigures to illustrate the general relations of the parts. The shaftcarries a wheel, D, below the cable-wheel B, this wheel D being toothedor recessed in such manner as to be adapted to be engaged with the bailof the bucket when the latter is passing around the terminal wheel, thebucket being carried by a pendant, G, joined to a clip, C, which isfastened to the cable, the bucket bail or pendant being held properlyrelatively to the wheel D by a guideor camtrack, D", which partiallysurrounds the shaft D, and the tipping of the bucket for emptying itbeing effected by a second guide or camtrack, D adapted to engagewiththe side of the bucket or an arm projecting downwardly therefrom.However, these parts last above described may be of the character shownin my aforesaid Patent No. 269,525, and therefore need not be dwelt uponhere.

In the aforesaid Patent No. 269,525 devices were shown in combinationwith the terminal wheel whereby the bucket could be emptied when thecable was situated in a substantially horizontal plane, the axis of theterminal wheel being in a corresponding positionthat is to say, on avertical line; but a cable tramway of this character may be availableunder another set of conditions prevalent in regions wherethese tramwaysare often necessary-that is to say, upon the sides of hills" ormountains.

A construction and arrangement of parts will be described whereby thecable may be allowed to lie in a plane more or less inclined .to thehorizon while it passes around the terminal wheel, the said wheel lyingin a parallel plane.

The wheel, together with its shaft, and the parts combined therewith aresupported upon any suitable frame-work adapted to hold the said parts atan inclination corresponding to the plane in which it is desired thatthe cable shall move.

In the drawings I have shown a frame-work, but wish it to be understoodthat I do not limit myself to the details of its construction thereinshown, having selected one which at present I prefer, but which may bemore or less varied as circumstances require.

The parts of the frame shown consist of one or more girts similar tothat above referred to at E, one or more longitudinal sills, E E,uprights E E, (see Fig. 1 and dotted lines, Fig.

2,) near the terminal wheel, the position of.

the upright E being indicated by dotted lines in Fig. 2, uprights E 'Eat a suitable distance therefrom, and top beams, E E joining, respectively, the uprights E E on one side and E E on the other. The mainframe-work thus constructed has attached to it a guide-rail, e, (seeFigs. 1, 2, and 3,) extending from a short upright, E near the terminalwheel to another short. upright, E near the upright E this guide-rail 6being so related to the track or guide D that together they shall form acontinuous guide. Another guide-rail, e, (seeFig. 3,) is secured to themain frame, it being fastened to the uprights E E and having,preferably, a metal face-plate, e, and above this a third guide or trackis provided, it consisting of a metal bar or plate, 6, secured to theouter face of a bar, 6 fastened to the frame. 1

e 6 represent guiding sheaves or pulleys, upon which the cable can restas it moves to' ward and from the terminal wheel, and of these anysuitable number may be employed.

WVhen the means above described are to be employed for supporting theterminal wheel at an inclination to the horizon, and for guidingproperly the cable and the buckets to and fro, it (said frame-work) canbe supported by a supplemental one below, consisting of any suitablenumber of sills, as at e, and uprights 6 6 (see Figs. 1 and 3,) togetherwith whatever braces and girts are required.

.Upon the main frame, still referring to Figs. 1 and 2, there is mounteda traveling carriage, which, also, in its details, may be of variousforms, the one shown having two downwardlyextending bars, F F, joined bycross-bars F F the latter being at or nearly at the top, and a thirdcross-bar at or nearly at the bottom, concealed behind, 6, Fig. 1. Thiscarriage is held in place upon the guide or track e by means ofanti-friction wheels or rollers F.

there being two or more engaging with the 7 upper edge or face of thetrack a, and two or more with the lower, whereby the whole carriage isheld properlyin position. The carriage is also provided with two or moregrooved sheaves or rollers, F upon which the cable can rest, so thatthere shall be no friction exerted upon the carriage by said cable.

f represents a rocking bar, mounted suitably, for instance, in hearingsin the upper crossbar, F and in the lower cross-bar. This rocking bar'fhas a laterally-projecting arm, f, which, when the parts are in theposition shown in Figs. 1 and 2, lies somewhat above the cable andacross the same in the path of the clips 0 It has also an arm, f in thesame plane (transversely of the barf) as is the bar 6', or its metalfacing-piece e the end of this arm f when the parts are in the positionshown in Fig. 1, bearing against the said facing-piece 0, so as toprevent the bar f from rocking; but when the parts have moved totheother end of their throw the bar 0 or its. facing-piece e" no longerengages with the arm f and therefore the latter does not prevent the barf from rocking or yielding to a force exerted upon the arm f at the top.

f is a-finger attached to the rocking barf, (see Figs. 1 and 15,) andwhich, when the parts are in the position shown in Fig. 1, lies ioo inthe path of the pendants or of the carriers sition shownin Fig. 1, andafter the carriage has been drawn'down to the terminal wheel in themanner to be described this weight returns it to the position shown inthe saidFig. 1. The weight may be arranged in the simplest way-that isto say,' the end of the rope may be tied to the carriage, the ropepassing over the pulley G down to the weight; or, to make it moreeffective in a well-known manner, the end of the rope may be secured tothe frame, as shown at g, and may be attached to the weight by means ofa block and pulley.

The operation of the devices above described is as follows: Then abucket approaches, the pendant which carries it is in a verticalposition, although the cable is inclined, (see' Fig. 1, dotted lines.)the pendant being preferably united to the clip,which is secured to thecable by ahinge-joint. The clip first passes over the sheave or pulley ewhen the latter is employed, then moves forwardover thesupportlug-sheaves F until the pendant O strikes the army and the clip 0strikes the upper arm, f, the latter action taking place shortly afterthe pendant strikes the arm f When these two contacts have beeneffected, the pendant will be thrust out of the vertical position intoone substantially perpendicular to the plane of the cable, (shown indotted lines, Fig. 1,) in

order that the bucket and the pendant may be properly received upon theterminal wheel and upon the rag or toothed wheel D. The onward movementof the cable after the contacts have been effected causes the carriageto move forward toward the terminal wheel, the escape of the clip fromthe armf and of the pendant from the arm f 3 being prevented by reasonof the bar f bearing against the part 6 which, as said above, holds therocking barf and the arms atff rigidly relatively to the cable; but whenthe parts have been advanced sufficiently far the arm f escapes from thepart c at the end c Fig. 1, and therefore the rocking barf is allowed toturn to yield to the pressure exerted by the clip and the pendant. Theparts are so relatedin size and position that this escape shall beeffected at the instant the clip (1 reaches the point 0 (see Fig. 2,)where the rectilineal part of the cable is tangential to the wheel. Asthe pendant O has been up to this time held substantially perpendicularto the plane of the cable A, it or the bail which it carries engageswith the rag or sprocket wheel D at a point corresponding to the point Cof contact of the clip with the terminal wheel. After the clip andpendant have been released from the carriage the weight G operates todraw thelatter back into the position shown in Fig. 1, readyto act in asimilar manner relative to the next bucket or carrier. A stop, as at Gmay be used, or any other suitable for the purpose of arresting thecarriage.

In order to prevent any back movement or rebounding of the pendant afterit has come in contact with the arm f, a stop, H, (see ward motion.

Figs. 1 and 16,) is employed, which is arranged to yield to the pendantas the latter moves inward; but after-it has passed the stop H movesoutward across its path to prevent its back- As shown, the stop H isformed upon or carried by the end of a flat spring, H, against which thependant presses as it moves in, (see dotted lines, Fig. 16,) and whicheffects the outward movement of the stop after the pendant passes.

I have also shown in the drawings the means which I have devised wherebya bucket may be emptied or not at certain points, so that a separationbetween the loads dumped by the various buckets may be permanentlypreserved. I

. It is well known that it is desirable to keep the ore produced by oneminer separate from that produced by another. I accomplish thisseparation, and preserve 'it by employing different bins or receptaclesand combining therewith devices by means of which certain of the bucketsshall be dumped into one bin or receptacle, and another or others shallbe dumped into another receptacle.

Referring to Fig. 7, I represents a camguide secured to the frame, andwhich is adapted to engage with the side of the bucket, or with an armprojecting therefrom to a greater or less distance, so as to effect adumping of the bucket and its contents into a bin or receptacle. Ofthese dumping cams or tracks as many may be employed as are the separatemasses which it is desired to obtain. The dumpers on the one hand, andthe buckets or carriers or the pins or projections carried by the latteron the other hand, are so related to each other that some of thecarriers shall engage with one cam or dumper and pass all others, whileanother set of carriers shall engage with another dumper and pass allothers, and so on to any extent desired.

The necessary variations of the dumpers relative to each other or of thebuckets or pins carried thereby can be readily effected, and to thoseacquainted with the art various methods will suggest themselves forvarying the parts relative to each other to accomplish these ends.

In Figs. 17 and 18 a cam is shown as being movable, the cam beingsupported in standards I 1 having bolts 2' in slots 2', though Ido notwish to be limited to the devices shown.

In Fig. 18 the dotted line indicates the normal vertical plane of thepin (1* on bucket O that is to say, the line on which said pin wouldmove were it not throwh out by the du n per.

The dumpingcam may be supported in any suitable way to accomplish thevarious ends aimed at. It is shown as mounted upon a frame-piece, but inthis respect there is wide range for variation.

In the construction shown each cam engages with certain of the bucketsor with the pins carried thereby, the latter being of sufficient ICUlength to engage therewith, and each of the other cams engages withanother set of buckets, the engaging portions being related to eachother differently from those of the other sets by means of a differencein position or length, &c.

The frame and carriage in Fig. 7 may be the same as in Figs. 1 and 2 andneed not be described.

I will now describe the means which I employ to effect the loading ofthe continuallytraveling buckets.

Referring to Figs. 8, 9, 10, 11, and 12, J J represent the longitudinalsills of a frame provided with suitable cross-girts, J J it having alsouprights J J at one end and J J at the other, and having at the top alongitudinal beam, J on one side and a platform, J Upon the generalframework thus described there are mounted two or more sheaves orpulleys, K K, upon which the cable rests as it moves over the frame.

j represents a track-bar,preferably of metal, secured to the sill orbeam J corresponding to that at 6 already set forth.

9' is a track or cam secured to the top of the platform J it consistingof a metal bar supported in any suitable way upon standards j, it havingat one end an inclined part, 9'

Upon the track-bar j there is mounted a traveling carriage having thefollowing parts:

L L are downwardly-projecting bars, joined by cross-bars L L L, the lasttwo being the one at the top and the one at the bottom.

L L are rollers fitting upon the top of the track j, and L L rollersfitting upon the under side.

M M are sheaves or rollers, carried by the carriage-frame, and adaptedto have the cable pass over them, they preventing frictional engagementbetween the cable and the carriage.

m is a rocking bar mounted in a plate, in, at the top and in acorresponding plate at the bottom. This rocking bar m has an arm, mlying in the path of the cable-clips, an arm,

of, lying in the path of the pendants, which support the buckets orcarriers, and an arm, m, which, when the parts are in the position shownin Fig. 10, bears against the platej.

The parts last above described-to wit, those indicated by L L L L L L Lm m m are analogous in structure and operation to the correspondingparts above described in the construction shown in Figs. 1 and 2.

There is a loop-like frame, Figs. 10 and 12, which surrounds the path ofthe buckets carried by the cable, and shown as having the parts N N N NN; but I do not wish to be limited to the exact construction shown, asit may be varied more or less. I prefer to have the part N extendsomewhat backward from the bar on, and the part N project downwardly toa point below the path of the buckets. The part N lies below and acrosssaid path, and is united to the part N which rises up on the outside ofsaid path. At N there is an ble. O. which carriesa roller, 0, adapted toride upon offset, or the frame is projected inwardly to or somewhat overthe upper or outer edge of the bucket.

N represents a plate rising from the part N. It carries a bin or hopper,O, of the form be delivered into the bucket carried by the ca- The binor hopper is closed by a slide, To this slide there is attached a bar, 0

the track j j is a bar or rod rising from the plate N it being fastenedto a cross-piece, M carried by an upwardly-rising support, M", securedto the carriage-frame L L L. The bar 0 1oose ly engages with the bar P,so that it can slide up and down relatively to the latter. (See Fig.10.) An upward movement of the bar 0 and of the slide 0 is caused by thecam or guide 3' j" when the carriage moves forward.

In order to assist in holding the loop-like frame N N N N N 4 steady, Imount a roller or friction-wheel, T, upon the under face of the part NBy preference this wheel or roller T lies horizontally, as shown inFigs. 10 and 12, and travels between guide-rails t t, mounted upon theframe-work, these guiderails being provided with metallic facingstrips11, when desired.

Q, is a guide-piece having an outwardlycurved end, as shown at 9 It canbe adjusted toward and from the bin or hopper by means of screws orother regulating devices, as shown at q q, Figs. 10 and 12.

Qis an opposite guide-piece,having a curved end, q", this curved end,together with the curved end of the other guide, being so arranged as toinsure that the pendant of the buckets shall move in the proper path.

R is a stop analogous to the stop above described, it, in this case,however, consisting of a pivoted bar bent to have an angular portion,1', in combination with a spring, T. It can yield to an incomingpendant, but after the latter has passed the part r said part swingsacross the path of the pendant and prevents the latter from movingbackward.

The operation'of the devices constructed and arranged as above describedis as follows, it being supposed that the bin or hopper O is loaded withmaterial and situated in the position shown in Fig. '10: Then as theempty bucket approaches, its clip first passes over the sheave K andthen over one or more of the sheaves M until it strikes the arm m, thependant of the bucket at the same time striking the arm in". As soon asthese contacts are effected the carriage is drawn forward by the cable,together with the loop like frame N N N N N t N 5 and the bin or hoppercarried by the latter. As the carriage and hopper move forward the slide0 is forced upward bymeans of the cam j j*, and after that the materialis permitted to drop into the bucket, the latter being held so that itcannot move away from S, which preferably passes over a the bin orhopper, as will be readily seen by examining the drawings. After thetransfer of the material has been effected the carriage reaches the endof the bar j, whereupon the arm m* can swing outwardly, and, as aresult, the arms m m are thrust out of the paths of the cable and of thependant, and the latter pass on disengaged from the carriage. Then theweight S operates to draw the carriage back to its initial position, theweight being connected with the carriage by means of the cord pulley, s,and is connected to an arm, 8*.

Having thus fully described the specific devices shown, in order that aclear understanding may be had of one form of mechanism embodying myinvention, I will say that I do not limit myself to all the detailsshown and described, for it will be apparent to any one skilled in theart to which the invention appertains that many of the parts may be moreor less varied without departing from the spirit of the several parts ofthe invention. Thus it is not necessary that the devices for unloadingthe carrier shall be of exactly the form shown, and, in fact, thereciprocating carriage may be used to steady the carriers and hold themin proper place under modified circumstances.

I in the claims appearing below describe the bucket and its supportasacarrier, and itwill be seen that the particular features in detail ofthis do not necessarily enter into the invention, as carriers of varioussorts may be used, if adapted to intermittingly engage with a carriagewhich can support them or hold them in a given position relatively tothe cable.

Again, it may be remarked that as regards the holding of the carrierproperly in a given position the essential feature consists in providinga stop which shall be impinged upon by some portion of the carrier orits support, and which will be adapted to hold the carrier in thedesired position, and adapted, under some circumstances, to throw itinto a position out of the normal. Thus, the partf acts as a stoptemporarily; not that it stops the motion of the cable or the onwardmovement of the carrier, but it insures that the carrier shall be in thedesired position, and in this respect this portion of the deviceoperates similarly in the construction shown in Figs. 1 and 2 forunloading, and in the construction for loading shown in Figs. 8, 9, 10,11, and 12.

\Vhen it is desired to unloadacarrier where the cable is inclined, thepart acting as a stop may be used to throw the carrier or carriersupportout of the normal position occupied when freely suspended; but, underother circumstances, it need not vary the position of the carrier-as,for instance, in Figs. 7, 8, 9, 10, &c.

In the claims below I refer to the means for unloading the carrier. Ihave shown several forms of devices for effecting this object, one formhaving the toothed wheel on the terminal wheel-shaft, the circular trackD, and the cam-track D another form (shown in Fig. 7) having astationary canrtrack, I, and another form, Figs. 17 and 18, having anadjustable cam-track; and prior to the date of my patent other meanshave been known for unloading cable-carriers; and therefore I wish it tobe understood that in the combina tions set forth in the followingclaims I mean to include not only the specific devices that I haveshown, but also those which are the equivalents thereof.

Again, it will be noticed thatI have shown and described (in order tohave the apparatus clearly understood) but one form of carrier orreceptacle 0, it being simple in construction, and I have alluded tothis in the claims below as a carrier or receptacle, 0; but it will beunderstood that any equivalent carrying device may be substitutedtherefor so long as the other features incident to this part of theinvention are preserved. for it is well-known at this day that not onlymay cable-carriers be provided with one pendant, but also that they maybe suspended by two, three, four, &c.,and with carriers of such species,loading and unloading devices having the characteristics of mine may bereadily combined. So, too, it is well known atthis day that in manyrespects tramways in which the cable is stationary and the carrier ismovable relatively thereto are similar to tramways of the specificcharacter which I have shown; and therefore I shall also apply to such astationary cable and movable carrier my devices for loading andunloading and my means for holding the carrier properly relatively tothe loading and unloading devices.

I do not in this application claim any of the features relating to thegripping devices which I have shown, or those relating to the clip orclamp for securing the carriers to the cable, as I have made these thesubject-matter of other applications for patent; nor do I claim any ofthe combinations claimed in my application No. 138,584, filed July 23,1884, or 104,917, filed August 27, 1883.
